Subject: [PATCH] [3.6] bpo-42103: Improve validation of Plist files.
|
||||
(GH-22882) (GH-23118)
|
||||
|
||||
* Prevent some possible DoS attacks via providing invalid Plist files
|
||||
with extremely large number of objects or collection sizes.
|
||||
* Raise InvalidFileException for too large bytes and string size instead of returning garbage.
|
||||
* Raise InvalidFileException instead of ValueError for specific invalid datetime (NaN).
|
||||
* Raise InvalidFileException instead of TypeError for non-hashable dict keys.
|
||||
* Add more tests for invalid Plist files..
|
||||

Subject: [PATCH] bpo-46623: Skip two test_zlib tests on s390x (GH-31096)
|

|

Skip test_pair() and test_speech128() of test_zlib on s390x since
|
||||
they fail if zlib uses the s390x hardware accelerator.
